Alt+Dragging Dynamic Link Clip in Timeline Duplicates Source
When you alt+drag in the timeline to duplicate a dynamic link clip, it will duplicate the source clip in the project panel as "[name] Copy 01"
This makes unnecessary project clutter? It should just link to the same source instead of making a new one. I couldn't find any preference to disable this behaviour and it also doesn't seem to happen consistently.
Please fix this so alt+dragging a dynamic link clip in the timeline will use the original source instead of creating a duplicate source.

This baffles me too. There is no live text in the linked AE composition, but the sequence has a text layer in one of its nested sequences).
alt+dragging creating a copy makes sense with the legacy text editor clips, and the older dynamic link template files where you'd change the text in the Effect Controls. Newer templates don't need it, however.
Changing the behavior completely would make working with older projects slightly more cumbersome, but it'd be nice if there was a way to toggle the behavior on/off or have two kinds of key combinations, like alt+drag for replace and alt+shift+drag for copy and replace.

Does your composition include text? It makes sense that it duplicates comps with live text so that you can make/edit multiple instances from the same template - eg for lower 3rds. This might be why you see it inconsistently - it might only occur on comps with text?
